. SAMUEL BALL, OF CHICAGO, ILLINOIS TOOL FOR VACUUM-CLEANERS.

To all whom it may concern:

Be it known-that I, SAMUEL C. BALL, a citizen of the United States, anda resident of the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Tools forVacuum-Cleaners; and I dohereby declare that the following is a full,clear,

and exact description of the same,-referencebeing had to theaccompanying drawings,

an improved nozzle adapted to readily pick up lint and the like, andcapable of use well for a general cleaning tool.

It is also an object of the invention to:

afford a tool whereby'the nap of rugs and the like may be combed, thebetter to remove the dust from the same and to improvethc appearance ofthe rug or other article;

It is also an object of this invention to afford a nozzle for vacuumcleaners in which the draft of the inflowing air shall be prac ticallyuniform for the entire length thereof,

' thereby assuring uniform action and highest efiiciency.

The invention consists in the matters hereinafter described and morefully point-- ed out and definedin the appended claims.

In the drawings: Figure 1 is a front ele- Vation partly broken away of adevice embodying my invention. Fig. 2 is a section on line 2-2 ofFig. 1. Fig; 3 is a bottom plan view of the nozzle, with parts omitted.Fig. 4: is an end elevation thereof.

In said drawings: Said nozzle is shown constructed integrally to afforda tubular socket piece 1, to receive the suction pipe leading to thecleaner, and a laterally extended and downwardly curved head 2, cast;

or otherwise constructed to afford an open floor slot for nearly theentire length thereof, and which is of maximum width at the ends and theinside walls of which curve inwardly on each side with uniformlydecreasing width to the center, at which oint said slot is at itsminimum width, an suf- Speciflcation of Letters latent.

ficiently restricted to compensate for the normally greater draft at thecenter occasioned by said portion being-in the direct line of draftfrom. the suction pipe connect-- ed in said socket. Said slot, mouth oropening, is curved outwardly at the ends to afford a relatively thin endwall and a perforation 3, is provided inisaid end wall to permit*'of asufficient inflow of air at each end to prevent the tool sealing bycontact with any surface capable of stopping the flow of air throughthe'mouth of the tool. At the mouth of said tool a relatively broadrecess 5 extending for substantially the entire length thereof, isprovided and in the bottom of which is the constriction beforedescribed. Outwardly converging slots are provided in the walls on eachside of said restricted mouth portion and'seated therein and extendingfor the entire length of the head on eachside of the mouthare combs 4,the teeth of which extend through said recess flush to the outer face ofthe tool. The teeth of said combs incline inwardly sufliciently toafford a recess between the same and the outer wall of the heachas shownin Fig's. 2 and 3, so that the air drawn inwardly beneath the head is atall times drawn directly between the teeth of The operation is asfollows: When the dev1ce is in use, as, for instance, in cleaning a.rug'or fabric of any material, or any other surface, any lint lyingupon the surface raised sufficiently by the inclined teeth for theinwardly flowing air to pass beneath the same, and thence carry such.lint or other material to the suction pipe. When used on any materialhaving a raised nap, as, for instance, certain types of rugs anddraperies, or upon any article or garment made. of fur, the combs 4,serve to comb the nap or fur in the presence of the strong inwardly andupwardly flowing current of air, thus combing, cleansing, aerating, andrenovating the same, removing therefrom any and all material that mayhave lodged on or within the same.

Whatever the length of the head may be, the opening or mouth therein isso proportioned as to afford a uniform draft of air for the entirelength of the tool, and in consequencg the device works with the sameeflicien-ey at any point in its length. Furthermore, hwing to the smallapertures 1n the ends of the'head, the maximum 'cfiiciency of the-toolis maintained at all times, inasmuch as there is always a sufficient airinlet provided to prevent the tool sealing upon the surface treated.

- Details of the construction may be varied,

and other devices may be incorporated there with as preference orconvenience may dietate. I do not pur ose limiting this application forpatent 0t erwisethan necessitated by the prior art.

I claim as my invention:

1. A tool or head for vacuum cleaners having a lon it-udinallyextendedmouth, the inner walls t ereabove converging upwardly. and from the endstoward the center.

2. A tool or head for vacuum cleaners having a longitudinallyextendedflmouth, the walls thereabove converging in a horizontal planefrom the ends toward the middle.

3. A tool'of-the class described having a relativel'. broad recessextending approximately or the entire length of the bottom thereof,walls above said recess converging in both substantially vertical andhorizontal planes toward one another affording a gradually decreasingarea of passage therebetween of narrower-width toward the middle.

4. A vacuum tool of the class described,

embracin a hollow elongated head, provided 7 with a re atively broadrecess ,in the bottom thereof and extending substantially the length ofthe tool, said recess communicat ing with an elongatedslot or mouthdecreasing in wldth from the ends tothe middle of the head, and a combon each side 'of said l mouth with the teeth thereof convergingdownwardly. 4

5. A vacuum cleaning tool comprising an elongated hollow head having astraight bottom containing a relatively broad recess extendingsubstantially the length thereof, and having a mouth or slot openinginwardly therethrough-at the center thereof and varying from its maximumwidth at the ends to its minimum width at the middle,

andconverging combs, one on each side of I said mouth or slot andprojecting into said recess, the teeth thereof finishing flush wlth thebottom of the tool.

*6. A vacuum cleaning tool comprising an elongated hollow. head having astraight bottom containing a relatively broad recess extendinsubstantially the length thereof and having a mouth or slot-openinginwardly therethrough at the center thereof and varying from its maximumwidth at the ends. to its minimum width at the middle, and convergingcombs, one on eachside of said mouth or slot and project-in into thesaid recess, the teeth thereof finis ling flush with the bottom of thetool, said tool having
